For high performance application developers, the PXH840 host adapter combines 128 Gbit/s performance with an application to application latency starting at 0.54 microseconds. Inter-processor communication benefits from the high throughput and low latency. Using the latest SmartIO technology software from Dolphin, applications can now access PCIe devices located in computers up to 100 metres way as if they was attached to the local system.

The optimized TCP/IP driver and SuperSockets™ software remove traditional networking bottlenecks, allowing standard IP and sockets applications to take advantage of the high performance PCI Express interconnect without modification. The overall framework is designed for rapid development of inter-processor communication systems.

The PXH840 card comes with a full license to the Dolphin eXpressWare software. The PXH842 Gen3 Adapter card does not include any software license and is well suited for high performance Transparent IO Expansion applications. The PXH840 card is fully supported in eXpressWare 5.5.0 and newer.

Supported topologies

Using the PXH840 card, you can connect two systems using PCIe Gen3 x4, x8 or x16 depending on the throughput requirements. You can also connect 3 systems using a x8 cable between each system.
